- To all ,wlzom it may concern: I

Be it'known that I, Rtindi.rn HorrMAN, a citizen of the United States,residing-at Chicago, in the county of Cook and State ofIlhnois, haveinvented certain new *and useful Improvements in Oil-Stoves, of whichthe following is a specification.

This invention relates to an improved means for detachablv securing aburner in place in an oil stove.

In the accompanying drawings, Figure 1 is a vertical central sectionalview illustrating'one embodiment of my invention. Fig. 2 is a view takenin the plane of dotted line 2 of Fig. 1. Fig. 3 is a view taken intheplane of dotted line 3 of Fig. 1. Fig. 4 is a section on line 4 4 ofFig. 3.

In the embodiment hertin shown 01 Llle invention, 1 denotes the body ofthe oil burner, said body consisting of an inner and an outer wick tubeconnected together at their lower ends to form a tubular receptacle forthewick and a small quantity of oil. Said receptacle is connected to afeed pipe 2 leading from a suitable reservoir (not shown) by the meansto be now described.

3 is an angular inlet connection rigidly secured to the outer wick tubeand adapted at its outer lower end to rest upon a shallow cup 4 securedto the pipe 2 by means of a tubular nipple Preferably a packing ring orgasket (3 is interposed between the cup 4 and the inlet connection 3.Said inlet connection is clamped against the packing ring by means of arigid yoke 7 having openings 8 therein for the reception of the pipe 2.Said yoke passes over the top of the inlet connection 3 and rests upon anut 9 through which extends a clamping screw 10, said screw also passingthrough an opening 11 in the yoke and bearing against the top of theinlet connection. It will be seen that when the clamping screw 10 istightened, the inlet connection 3 will be rigidly secured to the pipe 2.The upper side of the nut 9 is rounded, and the yoke 7 is correspondingly shaped so that the yoke may bear equally upon the pipe 2 atopposite sides of the cup 4. The opening 11 is elongated, as shown inFig. 2, so that the screw 10 shall be free to bear squarely upon theinlet connection. The openings 8 in the yoke are sufliciently large toallow for slight variations in the size of the pipe 2 with which. theyoke. is'lto beused: Thefiopposi'te side of the. body. .1 is detachablysecured. to

a suitable supporting-member, i-j'su'eh as -a' frame' bar 12 by.means-bf: two-arms 13f fixed, in this instance, to the. inner sideof'thein-"ib ner wick tube, said armslying at opposite sides of th framebar 12 and each arm having an angular lug l-i extendin into an openin inthe frame bar. It will be seen that a er the screw 10 has beenslackened, 66 and the yoke 7 turned on the axisof the pipe '2 until saidyoke is clear of the inlet connection 3, the body 1 maybe turnedsufiiciently to disengage the lugs 14 from the openings 1'5, whereuponthe body 'may be 70 lifted off the frame bar 12and the feed pipe 2. Thefeed pipe 2 and the frame bar 12 may extend substantially parallel witheach other, as herein shown. Said pipe and frame bar extend at the sidesof the burner instead '18 of acrpss the lower end thereof,,as in priordevices, and thus do not obstruct the free flow of air upwardly throughthe inner wick tube.

lwould have it understood that the invention is not limited to'theprecise details described except to the extent indicated in the appendedclaims. I claim as-my invention: Y

1. The combination of a burner body; an 86 inlet connection secured tosaid body; a feed pipe; means on said feed pipe arranged to be engagedby said inletconnection; a yoke having openings through its arms, saidpipe extending through said openings; a nut 90 within said yoke; and aclamping screw extending through said yoke and said nut and bearingagainst said inlet connection.

2-. The combination of a burner body; an inlet connection secured tosaid body, a' feed pipe; a cup on said feed pipe arranged to receive oneend of said inlet connection;

a nip le securing said cup to said pipe; a yoke iaving openings throughits arms, said pipe extending through said openings, said yoke passingover the top of said inlet connection; a nut within said yoke and a.clamphaving an angular portion arranged to. en- 1 9 age said-frame bar;a feed pipe; and means lioned opening being elongated in thedirecot-securing the opposite side of the burner tion of extension ofthe p pe; and a clampto said feed pipe.

: ing screw extending through said elongated 15 4. The combination of aburner body; an opening and said nut and bearing against feed pipe;means on said feed pipe arranged to be engaged by said inlet connection;.a

yoke having openings through its arms, said pipe extending through saidopenings; a nut within said-yoke and having a rounded side in contactwith the yoke,-- the latterhaving an opening opposite said nut, saidlast men- -in1et connection secured to said body; a said inletconnection.

In testimony whereof- I afiix my signature in presence of two witnesses.
